Chelsea manager Andre Villas-Boas has refused to apologise for post-match comments he made about referee Chris Foy after his side’s 1-0 defeat against QPR.
The 34-year-old was speaking shortly before the FA charged the Blues with failing to control their players and asked Villas-Boas to explain his comments.
However the former Porto coach has stood by what he said, in which he described Foy as being ‘card-happy’ and ‘unfair.’
"I don't think I said anything I shouldn't have," Villas-Boas told reporters. "I would never question the referee's integrity. But the fact is that, at the moment, we are paying heavily in terms of major decisions.
"Maybe this is what the FA [don't] want to hear from me - phrases like, 'The referee has influenced heavily three of our games'."
"If you go one route, you have to stick to it for the rest of the game.
"With 11 players, we should have played better and there are mistakes we have to avoid and which are fair - you have to be criticised and evaluate yourselves and learn from those mistakes - but it's a very disappointing day for the referee, for Chris Foy. I will stick to my words.
"Chris, for this particular game, was card happy and didn't show a pattern to what he's done in the past.
"What happened in that game was surprising given what he'd done before."
Jose Bosingwa and Didier Drobga were both red carded, while another seven team-mates received yellow cards in the hotly contested west London derby.
Villas-Boas who admitted speaking to referees’ chief Mike Riley for the second occasion this season to complain about the referring display, revealed the club will not be appealing Bosingwa’s red card and do not lack discipline.
"It might have put us in trouble for the Arsenal game, appealing Bosingwa's red card, and we weren't going to use him in the Carling Cup anyway.
"It's not indiscipline, it's not aggressiveness. There might be tactical fouls, that you have to allow. You have to respect.
"We didn't ever lose our discipline. We committed fouls because we were exposed, but that's not indiscipline."
Finally he refuted claims made by QPR midfielder Shaun Derry claim that Chelsea 'lost their heads' on during the game, snapping: "Fantastic Shaun Derry.
"You could ask Shaun Derry whether, playing against nine men, they might have done a bit better.
"Full praise to their commitment and to their strength, but they don't have to blow it out of proportion because we won't."
